Process status in linux

There are five states of a process on linux:

1. Run (running or waiting in the run queue)

two。 Interrupt (while dormant, blocked, waiting for the formation of a condition or receiving a signal)

3. Uninterruptible (unawakened and unrunnable upon receipt of the signal, the process must wait until an interruption occurs)

4. Deadlock (the process is terminated, but the process descriptor exists until the parent process calls the wait4 () system call to release)

5. Stop (the process stops running after receiving SIGSTOP, SIGSTP, SIGTIN, SIGTOU signals)

The ps tool identifies five status codes of the process:

D non-interruptible uninterruptible sleep (usually IO)

R runs runnable (on run queue)

S interrupt sleeping

T stop traced or stopped

Z zombie a defunct ("zombie") process
